Data Type: DS-73
This alert is generated by any change to the
static data. To support tracking changes in
static parameter values, the blocks static
revision parameter will be incremented each
time a static parameter value is changed. Also,
the blocks static revision parameter may be
incremented if a static parameter is written but
the value is not changed. If the Actual Mode is
not Out of Service and Reports is selected in
the Feature Select parameter, then this
parameter will be sent to the host system
providing the host has set up alert
communications. Changes to static data while
the block is Out of Service will be reported
when the block transitions to another mode.

Data Type: DS-72
This alarm is generated by a nonzero value in
the Block Error. parameter. This alarm has a
fixed priority of 2. For a BLOCK_ALM to be
broadcast to the host the following conditions
must be met:
The feature Reports must be selected
Alert communication with the host must be
setup
In the ALARM_SUM parameter, the disable
bit for Block Alarm must be clear.

Data Type: DS-74
0=clear, acknowledged, reported, enabled
Current alert status, unacknowledged states,
unreported states, and disabled states of the
alarms associated with the function block. The
Resource block only has two alarms: Write
Alarm and Block Alarm.

Priority of the alarm generated by setting
WRITE_LOCK to Unlocked.
Write Alarm
WRITE_ALM
40
Data Type: DS-72
This alarm is generated when Unlocked in the
WRITE_LOCK parameter is set. This alarm
has a priority of WRITE_PRI. For a
WRITE_ALM to be broadcast to the host the
following conditions must be met:
The feature Reports must be selected
Alert communication with the host must be
setup
In the ALARM_SUM parameter, the disable
bit for Write Alarm must be clear.
WRITE_PRI must be greater than 1.
